Endeavour Download Area

On this page you will find the Endeavour demonstration version, the ACD ChemSketch freeware version, and a quickstart manual in Spanish language.


If you are interested in the free-of-charge demo version, we would appreciate very much if you register for our mailing list. Although this is not mandatory for downloading the software from below, we would like to be able to inform you by e-mail when updated versions have become available.

As an alternative, you can follow us on Twitter where we also post information about updates and other news.


The Endeavour demonstration version runs in full-featured mode, i.e. without any restrictions, for 60 days, comparable to Match! but unlike Diamond demo version. After this period, the structure solution facility of the Endeavour trial version is restricted to the elements present in the tutorial's compounds (currently H, Li, B, C, N, O, Na, P, S, Cl, Ni, Cu, Mo, Ru, In, Ba, La, Au, Pb) and to carbon containing molecules with composition C14, C15NO2S, and C15H23NO2S. Besides this, there is a limitation in the 'Save' function: Saving files in Endeavour's proprietary format is disabled, whereas export into other formats ('Save as..') works.

Endeavour is distributed as compressed self-extracting file for most MS Windows 32-bit operating systems (XP, Vista, Windows 7, Windows 8/8.1, Windows 10) and can be downloaded via the link below. It is provided with a detailed tutorial and sample files. Please see the README.TXT document to learn how to install Endeavour and what has been changed in the latest update.

ACD ChemSketch

For the generation of three-dimensional molecule structures we recommend the ACD ChemSketch software. A freeware version of ChemSketch is included in the ENDEAVOUR package, however it is not included in the ENDEAVOUR demonstration version to keep the package as small as possible. You can obtain ACD ChemSketch freeware from
